"Congresswoman Bachmann's husband is of Swiss descent so she has been eligible for dual-citizenship since they got married in 1978," spokeswoman Becky Rogness said in a statement. "However, recently some of their children wanted to exercise their eligibility for dual-citizenship so they went through the process as a family."

And, according to an interview with Swiss TV, Bachmann, who is currently seeking a fourth term in Congress after her failed bid for the White House, is now also eligible to run for office in the tiny European country.

Asked if she'd be interested in seeking office in Switzerland, Bachmann joked that "there's a lot of competition ... and they're very good."
